- A
Use batch transform with two transform jobs chained together.
Why wrong: Batch transform is for offline processing, not real-time inference.
- B
Use an AWS Lambda function as a proxy to invoke the preprocessor and then the predictor separately.
Why wrong: Lambda adds complexity and latency; pipeline is the native way.
- C
Combine the preprocessor and predictor into a single Docker container.
Why wrong: Combining reduces flexibility and reusability.
- D
Create a PipelineModel in SageMaker with both containers listed in order: first preprocessor, then predictor.
PipelineModel automatically sends the output of the first container as input to the second.

MLA-C01 Practice Question: An ML engineer creates a SageMaker inference…
This MLA-C01 practice question tests your understanding of mla-c01 exam topics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An ML engineer creates a SageMaker inference pipeline with two containers: a preprocessor and a predictor. The preprocessor is a lightweight Python script that transforms input data. How should the engineer structure the endpoints to ensure both containers run sequentially?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a PipelineModel in SageMaker with both containers listed in order: first preprocessor, then predictor.
Option D is correct because SageMaker's PipelineModel allows you to define an ordered sequence of containers that are executed sequentially within a single HTTPS endpoint. When an inference request is made, the preprocessor container transforms the input, and the output is passed directly to the predictor container, all within the same endpoint invocation. This ensures low latency and tight coupling without needing external orchestration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume chaining containers requires external orchestration (like Lambda or separate jobs), but SageMaker's PipelineModel natively supports sequential container execution within a single endpoint, which is the simplest and most efficient approach.
Detailed technical explanation
How to think about this question
Under the hood, a SageMaker PipelineModel creates an inference endpoint backed by an NGINX reverse proxy that routes requests through each container in the defined order, using the `ContainerHostname` and `InferenceExecutionConfig` to control the sequence. The preprocessor container must output data in a format the predictor expects, typically via stdout or a shared volume, and the entire pipeline is managed as a single SageMaker model entity. In real-world scenarios, this pattern is critical for tasks like tokenization before a large language model, where preprocessing must happen inline to avoid serialization overhead.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
